Looking at the federal court decision [1], it looks like the patent was predated by an implementation that was demonstrated at SIGGRAPH, and apparently the creator of that gave the source code to the plaintiffs?!

"Lau further testified that, at the SIGGRAPH '95 conference, he performed live demonstrations of SRI TerraVision to at least 500 people, and in fact “gave [ ] the source code to TerraVision” to Art+Com employees who were in attendance and “walk[ed] them through the source code.”"

Didn't Art+Com demo their version in 1994?

The court case was based on the patent date? which would be later?

Kyoto (first demo) was at the end of 1994.
